I'm not entirely sure, but I don't think the cooler was secured properly and it was simply turning itself off everytime. I hope it still overclocks fine. I reapplied AS5 and turned it on, and it ran fine, posting with it now. I don't think I'll risk taking my Q6600 apart though
Some website pulled the heatspreader off, it wouldn't post after that. It might work, and it might not. Glad it works though. You should lap the heatsink if you haven't.
@ worshipme, how concave was the IHS? I started on mine with 800 grit, the corners were the high points. I'll post a pic if I've still got one hosted online.
EDIT: Must have deleted the pics last time I cleaned out.
I wouldn't try removing the IHS, I've seen reports of the core being ripped from the die due to the new thermal epoxy they use, it was OK to expose the core on the older AMD/Intel cpus but not something to be attempted with C2D or Dual core cpus
Good to see you got the Q6600 running again, panic attack over.
The corners were the high points like yours. It took me about an hour to get the IHS with 600 grit. I now see why it's important to be patient when lapping.
